Atmospheric phenomena over the Rocky Mountains can be sudden and dramatic.

Sundogs and Halo. Photographed near Grand Junction. This is caused by refraction from high altitude ice crystals.
Moonrise and Nightrise over Castle Mountain, Guffey, CO. November 15, 2005 UT 23:58. This image was made just one hour before the full Moon, and the geometry of the Sun, Moon, and Earth can be seen in the shadow of the Earth rising in the sky. The Moon is precisely on the edge of that shadow, in the penumbra, demonstrating that the three bodies are very nearly lined up, with the Earth between the Sun and Moon. Canon 300D @ 45mm FL, ISO 200, 1/100 second, f/4.5. Click image for a larger version.

Crepuscular Rays
Crepuscular Rays. Digital image with Canon 300D. What is seen is the contrast between light rays and shadows from distant clouds cast by the Sun and scattered by dust or moisture in the atmosphere. The rays appear to diverge from the Sun's position just below the horizon.
